NXT-4D - Four Door/Eight Reader Controller

Now with the ability to manage 8 readers for In/Out requirements when using Mercury Powered firmware option and NXT Readers

The NXT-4D - Four Door/Eight Reader Controller is built for today's IT environments. With all Ethernet functionality built directly into the controller, Keri's proprietary MAC address allows for reliable hardware discovery and true 1 button autoconfiguration. By using an existing TCP/IP network, controller cabling costs can be eliminated, or by using inexpensive unshielded CAT5 cable if building a new network they can be reduced up to 50% over traditional hard-wired access systems. The NXT-4D is designed to be extremely intelligent with little reliance on network traffic for decision making allowing it to be extremely thrifty with any network's valuable bandwidth.

To expand the system's capabilities, up to four companion 4 x 4 Input/Output boards (NXT-4X4) can be added - one to each of the controller's RS-485 trunks (busses). Customers can choose between Keri's new line of highly secure, 4-wire NXT Proximity Readers with reader supervision, and any reader with a standard Wiegand output or Keri's MS Series Proximity Readers via the NXT-RM Reader Interface Module. To manage the system, Doors Net software has much of the same look and feel as Keri's acclaimed original Doors software, but with the added functionality of Client/Server architecture and a host of advanced features. For even greater functionality, customers may opt for the Mercury Powered option.
